大型地下储煤槽仓超深基坑多种支护技术应用

摘要

Taking the raw coal storage tank engineering in a coal preparation plant replacement and extension as an example,this paper discussed the anchor soil nail,support pile and beam,conduits inner support and other large underground coal storage bin ultra deep foundation pit support tech-nology,introduced the technology process of each support technology,reduced the earth excavation and backfilling,shorten the construction period.%以某选煤厂改扩建原煤槽仓工程为例，对土钉锚杆、支护桩及冠梁、暗道内支撑等大型地下储煤槽仓超深基坑支护技术进行了论述，介绍了各支护技术的工艺流程，减少了土方开挖和回填量，缩短了施工工期。
